Dynamic trust model based on trade weight for P2P network
P2P网络中基于权重的动态信任模型*

Directing at the shortcomings of the existing model and drawing on the human habit of trust assessment and the main factors involved in transactions, this paper proposed a dynamic trust model based on trade weight for P2P network. While assessing the node trust value, the model put emphasis on the effect of trade weight on trust value, and specifically provided the method for trust value computing and the simulation. Results of the simulation show that the trust model can accurately reflect the current node trust value, and effectively resist the strategic deception and dishonest feedback.
